Fig. 2 is a view partly in elevation and partly Heretofore, when it was desired to erect radiov in Section, illustrating the manner of uniting two masts of considerable height, recourse was usually 'of the pipe sections to eachother, where the l0 had to structures of the lattice girder type, which same is done in the shop, and ordinarily known 19 structures are quite expensive and difllcultto as a fsh'op Joint: v

as shown in Figs. 2 and 3,'in order that the internal diameter of the same may be brought to the proper diameter to engage the outer surface of the end of the smaller tube whichis Vtelescoped therein. This reduction of diameter of the outer tube may be done by the well known swaging operation, the swaging being carried to such point that a proper shrink ilt may be made to hold the end portion of the smaller tube within the end portion of the outer-tube. This type of joint is well known in the industry, and4 is commonly used in the construction of tubular columns such as are used for agpoles and trolley poles, and for other similar purposes. The joint may also be reinforced by welding or otherwise if' desired.
Each of the several columns is held in 'fixed position at its respective ends, and for. this purv sections `of. successively smaller diameter constructed in a manner similar to the ordinary telescopic pipe type of ilagpole, the sections being joined to each otherby'means of joints such as are illustrated in Fig. 2 of the drawing.
By the foregoing arrangement, there will be provided a radio mast whichy may be made of considerable height, yet, while beingv relatively light and inexpensive, will be of suiiicient rigidity and strength to withstand the strains to which such structures are ordinarily subjected.
Furthermore, it has been found in practice that radio masts constructed as herein set forth and used for their intended purpose as vertical radiators have been found to have greatly improved radiating eiiiciency over the structures heretofore used for this purpose.
I claim:
pose the upper end section of each of the several/ 1. A radio mast comprising a plurality of sucolumns `may be provided externally with a plurality of radially extending ears or lugs I3 to which the stay or guy wires Il are attached by means of socket connections I5 of any preferred type. 'Ihe guy wires Mextend to suitable anchor blocks I6, which are properly located for the effective stabilizing of the mast. Ordinarily, each of the guy wires I4 will also be provided at various points throughout its length with strain insulators I1 of any preferred type, such as are well known and -commonly'used for insulating the guys ofradio masi-` structures.
Preferably each of the columnswill be so made as to comprise initially a separate unit of convenient length for shipping, and adapted to .be
joinedat its ends to the other sections above and .below the same by means of a eld joint, such, for example, as is shown in Fig. 3 of the drawing. For the making of t this eld joint, the outer Pipe, which ordinarily will be the top section I2 of vone of the columns, is reduced to suitable diameter, by swaging yin the shop, and a suitable ring I8 is inserted therein and welded or otherwise permanently secured thereto, being posiqtioned a sulcient distance from the end as shown in Fig. 3 of the drawing, whereby said ring will serve as a stop or seat when the end portion of the lowermost section Ill of one column is inserted 'inthe top portion of the uppermost section I2 of another col The lower end of the Amast may be supported on Aa. suitable insulator I9 which in turn may be supported on a suitable foundation block 20.
In the erection of the mast, the lowermost sec- A tion A is first mounted upon the base insulator I9 being positioned vertically thereon; Vwhereupon its set of guys I 4 are attached to each of the lugs I3 at the top thereof, thus providing a rigid lower portion into whichy the next column B maybe mounted. The lower end of the lowermost section I0 of the column B is then slipped into the upper end of the uppermost section I2 of the column A until the lower end of the lowermost section of-column Bv rests upon the supporting ring Il, as shown in Fig. 3 ofthe drawing.l Column B is thenstayed by its set of guys Il, and thereafter, step .by step, each of the other columns yis successively positioned with respect to thecolumn immediately below the same. The placing of the columns successively one above the other may be readily accomplished by suitable rigging (notY shown), but with which those 'skilled in the, art ofl erecting ilagpoles and the like are quite familiar.
The upper end of the mast may comprise an 75 extending section F made vup of a series of pipe in diameter than the section at the middle thereof, the lower section of each column being rigidly Joined to. the upper .section of the column immediately below the same, and means for indi- `vidually staying the ends of each of thecolumns.
2. A radio mast comprising a plurality of superposed columns,l each of said columns comprising a plurality of tubular sections joined to each other at their respective ends, the sections at each end of each column being smaller in diameter than the section atY the middle thereof, the lower section of each column being rigidly joined 'to theupper section of the column immediately below the same, and means for individually staying the ends of each of the colum 3.' A radio mast comprising a plurality of superposed columns, each of said columns comprising a plurality of tubular sections having their ends united by telescopic joints, the sections at eachyend of each column being smaller in diameter than the section at the middle thereof, the
lower section of -each'column being telescoped within the upper section of the column immediately below the same. and means for individually staying the ends of each of the columns.
4. A radio mast comprising a plurality of superposed columns, each of said columns comprising a plurality of tubular sections having their ends united by telescopic joints, the sections at each end of each column being smaller in diameter than the section at the middle thereof, the lower section of each column being telescoped within the 'upper section of the column immediately below the same, and a plurality of sets of guys respectively connected adjacent the upper ends of the respective columns. l

A radio mast comprising a plurality of superposed columns, each of said columns comprising a plurality of tubular sections joined to 4 tions at each end of each column being smaller each other at their respective ends, the sections at each end of each column' being smaller in diameter than the section at the middle thereof, the lower section of each column being rigidly joined to the upper section of the column immediately below the same, a plurality of sets of guys
